The Sign of the Four » (Unabridged)

Sir Arthur Conan Doyle was both a doctor and a believer in spirits, which may partly explain why his Sherlock Holmes is one of literature's most beloved detectives: Holmes always approaches his cases with the gentility and logic of a scientist, but the stories are suffused with an aura of the supernatural. Narrated by devoted assistant Dr. John H. Watson, Holmes's adventures were so addictive that fans protested the master deducer's "death" in 1893 and Doyle had to resurrect him.

Once a year, Mary Morstan receives an anonymous package containing a magnificent costly pearl. Aware that the gifts are somehow connected to the disappearance of her father ten years previously, she is both intrigued and frightened by the arrival of a letter summoning her for a meeting in the dead of night. Accompanied by Holmes and Watson, Mary embarks on a quest which is to lead them through the dark heart of the city, to a one-legged man and an incredible tale of greed and revenge.

Clive Merrison stars as Holmes with Michael Williams as Watson in this adventure, part of the unique fully dramatised BBC canon of Conan Doyle's short stories and novels featuring the world-famous sleuth.
